Prior to this commit we were keeping a count of how many KeyUpdates we have processed and failing if we had had too many. This simplistic approach is not sufficient for long running connections. Since many KeyUpdates would not be a particular good DoS route anyway, the simplest solution is to simply remove the key update count. Fixes #8068 Reviewed-by:

Fixes #7950 It was reported that there might be a null pointer dereference in the implementation of the dasync_aes_128_cbc_hmac_sha1() cipher, because EVP_aes_128_cbc_hmac_sha1() can return a null pointer if AES-NI is not available. It took some analysis to find out that this is not an issue in practice, and these comments explain the reason to comfort further NPD hunters. Detected by GitHub user @wurongxin1987 using the Sourcebrella Pinpoint static analyzer. Reviewed-by:

This commit adds a simple unit test to make sure that the constant-time flag does not "leak" among BN_CTX frames: - test_ctx_consttime_flag() initializes (and later frees before returning) a BN_CTX object, then it calls in sequence test_ctx_set_ct_flag() and test_ctx_check_ct_flag() using the same BN_CTX object. The process is run twice, once with a "normal" BN_CTX_new() object, then with a BN_CTX_secure_new() one. - test_ctx_set_ct_flag() starts a frame in the given BN_CTX and sets the BN_FLG_CONSTTIME flag on some of the BIGNUMs obtained from the frame before ending it. - test_ctx_check_ct_flag() then starts a new frame and gets a number of BIGNUMs from it. In absence of leaks, none of the BIGNUMs in the new frame should have BN_FLG_CONSTTIME set. In actual BN_CTX usage inside libcrypto the leak could happen at any depth level in the BN_CTX stack, with varying results depending on the patterns of sibling trees of nested function calls sharing the same BN_CTX object, and the effect of unintended BN_FLG_CONSTTIME on the called BN_* functions. This simple unit test abstracts away this complexity and verifies that the leak does not happen between two sibling functions sharing the same BN_CTX object at the same level of nesting. Reviewed-by:

Because test order can be randomized, running foo_init() as a separate test is unsafe practice. Instead, we make it possible to call it multiple times, and call it at the start of each separate test. Reviewed-by:

- Add a bit more text about that is expected of the user or OSSL_METHOD_STOREs. - Clarify what a method and what a numeric identity are. - Change all mentions of 'implementation' and 'result' to 'method'. To clarify further: OpenSSL has used the term 'method' for structures that mainly contains function pointers. Those are the methods that are expected to be stored away in OSSL_METHOD_STOREs. In the end, however, it's the caller's responsibility to define exactly what they want to store, as long as its 'methods' are associated with a numeric identity and properties. Reviewed-by:

Properties are a sequence of comma separated name=value pairs. A name without a corresponding value is assumed to be a Boolean and have the true value 'yes'. Values are either strings or numbers. Strings can be quoted either _"_ or _'_ or unquoted (with restrictions). There are no escape characters inside strings. Number are either decimal digits or '0x' followed by hexidecimal digits. Numbers are represented internally as signed sixty four bit values. Queries on properties are a sequence comma separated conditional tests. These take the form of name=value (equality test), name!=value (inequality test) or name (Boolean test for truth). Queries can be parsed, compared against a definition or merged pairwise.

The add/double shortcut in ecp_nistz256-x86_64.pl left one instruction point that did not unwind, and the "slow" path in AES_cbc_encrypt was not annotated correctly. For the latter, add .cfi_{remember,restore}_state support to perlasm. Next, fill in a bunch of functions that are missing no-op .cfi_startproc and .cfi_endproc blocks. libunwind cannot unwind those stack frames otherwise. Finally, work around a bug in libunwind by not encoding rflags. (rflags isn't a callee-saved register, so there's not much need to annotate it anyway.) These were found as part of ABI testing work in BoringSSL. Reviewed-by:
